keep cool man, 6s racing setup is not common. My 2 cents : you calculate the RPM to compair to a regular 4s setup.
like : 4s x 1900 kv = 39000
and
6s x 1350 kv = 34000
now you want the same speed for the center diff : most use 19/44 = 0.43
39000x0.43 = 16770 rmp on the center diff
34000/16770= 0.49 almost 0.5 so 44 / 2 approx 21 tooth on the pinion gear
my guess is that you should start with a 21 tooth pinion to see how it handles in real life
